Repeater Loopback

A Repeater Loopback (RLB) loops the signal being sent from the DSX-1 port back
to the DSX-1 port.

T1-to-T1 Repeater Loopback

T1-to-V.35 Repeater Loopback

Procedure

To run a Repeater Loopback:

1. Position the cursor at the Start command next to Repeater Loopback on the

Network & DSX-1 Tests screen.

2. Press Enter.

The Start command is changed to Stop.

3. To manually stop the test, verify that the cursor is positioned at the Stop

command.

4. Press Enter.

The Repeater Loopback cannot be started when any other loopback test is
in progress.

NOTE:

Activating the Repeater Loopback test causes the Embedded Operations
Channel (EOC), used for management, to be lost to the remote unit.
